Embodiment 1

[0040] Embodiment one: refer to figure 2 , is a kind of inspection well flexible interface structure disclosed in the present invention, the reserved hole 2 of the inspection well 1 is provided with a socket 4, and the socket 4 is provided with an inclined surface 41 along the direction away from the side wall of the inspection well 1, parallel segment 42 and a flaring segment 43 that expands the diameter outward, and the flaring segment 43 is arranged at the entrance of the socket 4 . Such as figure 2 and image 3 As shown, the end of the drain pipe 3 is provided with a socket 31. The socket 31 includes a circle of grooves opened around the end of the drain pipe 3 and a circle of flanges 311 formed after the grooves are opened. The flange 311 is sleeved with The first sealing ring 312, the first sealing ring 312 is made of rubber, and the cross section of the first sealing ring 312 is square.

[0041] When installing, insert the socket 31 sleeved with the first sealing r...

Embodiment 2

[0042] Embodiment 2: An inspection well flexible interface structure, the difference from Embodiment 1 is that, as Figure 4 As shown, at the junction of the parallel section 42 and the inclined surface 41, a circle of clamping grooves 44 perpendicular to the axial direction of the socket 4 is provided, as Figure 5 As shown, after the first sealing ring 312 is set on the socket 31, the diameter of the first sealing ring 312 is slightly larger than the socket 31. During the process of inserting the socket 31 into the socket 4, the parallel section 42 is extruded to make the first The sealing ring 312 is squeezed in after being compressed and deformed, and the outer wall of the first sealing ring 312 snaps into the slot 44 after being put in place. The slot 44 can make the first sealing ring 312 be better fixed in the socket 4, thereby This makes the installation between the socket 31 and the socket 4 more stable, and the sealing performance is better.

Embodiment 3

[0043] Embodiment 3: An inspection well flexible interface structure, the difference from Embodiment 2 is that, as Figure 6 As shown, the flange 311 of the socket 31 is provided with an inclined extrusion surface 3111 corresponding to the inclined surface 41 of the socket 4, as Figure 7 As shown, when the socket 31 is plugged into the socket 4, the inclined extrusion surface 3111 can be in conflict with the inclined surface 41, thereby filling the gap between the inclined surface 41 and the socket 31, so that the socket 31 and the socket 4 can be more closely matched. Tighter, better sealing.

Abstract

The invention relates to an inspection well flexible interface structure. The inspection well flexible interface structure comprises a bell mouth located on a reserved hole and a socket on a drainagepipe, wherein the bell mouth comprises an inclined surface, a circle of flange is arranged at the end of the socket, a circle of first sealing ring is arranged on the flange in a sleeve mode, when thesocket and the bell mouth are used for inserting, and the first sealing ring abuts against the inclined surface. According to the structure, the effect of improving the sealing performance between the bell mouth and the socket is achieved.

Description

technical field [0001] The invention relates to the technical field of inspection wells, in particular to a flexible interface structure for inspection wells. Background technique [0002] The inspection well is used in the building area (residential area, public building area, factory area, etc.) to buried three plastic drainage pipes with an outer diameter of no more than 800mm and a buried depth of no more than 6m. It is generally located at the intersection and turning of the three drainage pipes , pipe diameter or slope change, water drop, etc., in order to facilitate regular inspection, cleaning and dredging, or cemented well-shaped structures for downhole operation and inspection. [0003] Such as figure 1 As shown, the side of the well chamber of the existing inspection well 1 is provided with a reserved hole 2, and the reserved hole 2 is used to install the drain pipe. In the prior art, the drain pipe is inserted into the reserved hole 2, and then the drain pipe A...
